Pulmonary endarterectomy (PEA) is a well-established procedure in the treatment of chronic thromboembolic pulmonary hypertension (CTPH). The procedure is known to increase functional outcome and to raise the 5-year survival rate. We report 2 cases of pulmonary valve endocarditis and secondary embolisms causing sustained pulmonary hypertension. Both were treated with ...

We evaluated associations between cerebral blood flow (CBF) and histopathological features in atherosclerotic lesions of the internal carotid artery. Cerebrovascular reactivity (CVR) and CBF were measured in 72 patients with unilateral carotid artery stenosis who underwent Xe-CT before carotid endarterectomy. Collateral blood flow was estimated as stump pressure. Proportions of ...

Transthoracic Doppler echocardiography (TDE) is a non-invasive and easy reproducible method to assess the left internal mammary artery (LIMA) graft patency after coronary artery bypass graft surgery (CABG). LIMA graft dysfunction is rare, its rate being 10% at 10 to 15 years after revascularization. The most common cause of graft ...

Harms technique of C1-C2 fixation for atlantoaxial complex becomes more popular due to good fusion rate and low vertebral artery injury (VAI) rate. But considering the unique and variable anatomy of atlantoaxial complex, iatrogenic VAI will result in catastrophic consequences and provides particular surgical challenges for surgeons. To our knowledge, ...

ABSTRACT: BACKGROUND: Iliac artery atherosclerotic disease may cause intermittent claudication and critical limb ischemia. It can lead to serious complications such as infection, amputation and even death. Revascularization relieves symptoms and prevents these complications. Historically, open surgical repair, in the form of endarterectomy or bypass, was used. Over the last ...

In-stent restenosis in the femoropopliteal artery is common (20%-40%). Treatment of in-stent restenosis is challenged by poor patency rate. An ePTFE-covered stent-graft (Viabahn) is inert with a very small pore size that does not allow for significant tissue in-growth. Use of a Viabahn stent-graft may improve the patency rate in ...

Arterial aging, characterized by arterial stiffening that is clinically evaluable as aortic pulse wave velocity, is risky for CV events, disability, and loss of cognitive function. Today the only adopted strategy to decrease arterial aging/ arterial stiffness is represented by decreasing BP. Selective antihypertensive drug classes (calcium channel blockers, converting ...

Percutaneous device closure of atrial septal defect (ASD) is an alternative treatment to surgery. The main advantages of the percutaneous approach include avoidance of surgery, short procedure time and hospital length, in addition to comparable rates of complications. However, percutaneous device closure is associated with infrequent early and late complications ...

Coronary artery bypass grafting (CABG) remains the standard of care for multi-vessel coronary disease. However, the increased rate of peri-operative stroke reported after surgery compared to percutaneous coronary intervention (PCI) remains of concern. Anaortic, total-arterial, off-pump coronary artery bypass (OPCAB) grafting is a technique that offers the main advantages of ...

Proximal Protection Devices, either flow-reversal or flow-arrest demonstrate excellent results of acute- and short-term outcomes in patients undergoing carotid stenting. Intolerance rates of both devices varies from low (1.8%) to relatively significant one (up to 19.0%), according to the definition used in the studies. Interestingly, when accounting only the cases ...

The generally accepted treatment for infected aortic aneurysms involves open surgical resection and debridement, with in situ or extra-anatomical bypass. Occasionally, endovascular management can be substituted for the standard operation dependent on the patient's condition. We report the case of an 81-year-old female with a ruptured infected aortic aneurysm and ...

Percutaneous coronary intervention of complex true bifurcation lesions often fails to ensure continuous stent coverage and strut apposition in both the side branch and main vessel. Struts left unopposed floating in the lumen disturb blood flow and are increasingly recognized as increasing the risk of stent thrombosis. In this study, ...

Nonmaturing or dysfunctional hemodialysis fistulas are often repaired with interposition grafts placed either within the fistula (fistula-to-fistula configuration), or connected to another vein (fistula-to-vein configuration). The goal of this study was to compare the survival and usefulness of the composite accesses thus created, which we call "graftulas," with upperarm grafts. ...

OBJECTIVES: Internal mammary arteries graft failure in coronary artery bypass grafting (CABG) is mostly considered to be a result of competitive flow (CF) from the native coronary artery, which significantly limits future revascularization options. METHODS: With the left internal mammary artery (LIMA) anastomosed to the left anterior descending (LAD) coronary ...

BACKGROUND: Confirming the presence of arteries crossing the osteotendinous junctions (OTJs) of the rotator cuff may explain why rates of avascular necrosis (AVN) of the humeral head vary between three- and four-part proximal humeral fractures. It is hypothesized that the humeral head remains better vascularized in three-part fractures because one ...

The management of traumatic injury of the common carotid artery has traditionally required a conventional surgical intervention, which is associated with a high mortality rate. Endovascular procedures might offer a less invasive alternative to treat these injuries, with a lower rate of mortality and morbidity. We report the case of ...

Aging is associated with increased retrograde and oscillatory shear in peripheral conduit arteries of humans. Although the mechanisms responsible for these age-related changes are not completely understood, augmented downstream α-adrenergic tone likely plays a significant role in this phenomenon. Therefore, in protocol 1, brachial artery diameter and blood velocity were ...

Takayasu arteritis (TA) is a large vessel vasculitis that involves the aorta, its major branches and pulmonary arteries. Diagnosis of TA during childhood remains challenging due to the non-specific symptoms. We report a four-year-old girl presenting with fever, fatigue, weight loss, and elbow pain who was later diagnosed as childhood ...

We have proposed a novel short-duration thermal angioplasty with uniform temperature distribution. Although the dilatation mechanism of our short-duration heating dilatation was reported in our previous study, the influences on smooth muscle cells (SMCs) are not sufficiently understood. We studied the influences on SMCs in terms of shape change and ...

Vascular catheter use for dialysis remains highly prevalent, however, it is frequently adversely affected by access recirculation (AR). We previously reported the utility of effective ionic dialysance (EID)/blood flow rate (Qb) ratio in identifying significant (>5%) AR in arteriovenous (AV) fistulas (Mohan et al ASAIO J 56:427-433, 2010). We present ...

STEMI and unstable acute coronary syndromes are associated with widespread adrenergic activation which may increase radial artery (RA) spasm, requiring cross-over to the femoral artery (FA) during percutaneous coronary intervention (PCI). We assessed the incidence of failed trans-radial artery PCI in emergency cases compared with non-emergency cases. PCI procedures performed ...

Treatment of acute ischemic stroke (AIS) is an evolving field. New treatment options are still needed in order to achieve greater success rates for arterial recanalization. Intra-arterial therapy (lAT) is an option for AIS patients who are not good candidates for intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA) or where ...

The intracranial stent functions primarily to prevent protrusion of coils into the parent vessel during the embolization of wide-necked cerebral aneurysms and might also reduce aneurysm recanalization rate. In spite of these advantages, little is known about the long-term interaction of the stent with the parent vessel wall. We present ...
